MAG delrin case pics

[Dave]

Sorry guys I didn't get to this last week like I said I would.
Been very busy at work and I was out last weekend with the flue.

Here is some links to the Delrin case retail MAG model.

I used the C-System retail head model for these pic's, as that is all we had "open" around the office.

Before you ask, it is the industrial version of these head units that uses up all our components, and we have only recently increased our supply to offer the retail units as well. The retail version uses a micro channel style cooling block, and performance is about 6 l/m at 2.3M head. We will be installing other companies cooling blocks into this unit as well.

Thanks for the great idea, I think the cases look good given we have yet to mold them

those look nice good job

The Derlin is fantastic, however, myself and I'm sure many others are still questioning the use of aluminum in various pieces of the pump (or is it only the fittings?). Whatever the case is, corrosion is one of the big problems that plagued earlier CSP models, whats to stop it from doing the same this time. I've read about the new process CSP is using on the aluminum called Anolok, however I am not aware of the performance of this method, only that it is stronger than anodizing. Would you be able to elaborate on this?

After what Cathar has cautioned about AL and the G5, no way would I take a chance, sorry.

[Dave]

There is no AL exposed to the liquid, except one bearing case, which needs AL for proper support. All the "insides" of the pump is plastic except stainless steel shaft and jeweled bearings.

Personally I never seen any 750's come back because of corrosion.
Even so people asked for this and we provided

[EnJoY]

One bearing or ten bearings, it can all still corrode...especially with silver in the loop as such with a G5 or Silver TDX, however rare those may be. What are the guarantees that this metal bearing won't corrode?

[Dave]

It's not metal, it is jeweled.
Sapphire is ALO2 as is the bearing mount, the worse that can happen is that they bound to each other, which is a good thing.

Ceramic, sapphire, ruby, and anodizing are all ALO2, the difference is in there crystal structure.

[EnJoY]

Yea, but with copper or worse yet, silver blocks, in your loop...those metals will attack whatever aluminum is exposed and cause it to corrode. Normally, anodizing would prevent such a thing, but because of the fast movement of water in a loop..especially in the pump, this anodizing wears off slowly and eventually exposes the aluminum. There is no avoiding this and even the best anodized aluminum (swiftech blocks) have overtime been reported to corrode. Again, I realize it's only one bearing case that you say is exposed to water...but if that corrodes then what? Will the pump malfunctions? Will flow be hindered? Worse yet, will it cease operation?

[Dave]

Again all that will happen is the bearing will be more secure in its mount.
I think you need to look up jeweled bearings and at the pump itself

Days over, see all next weekend.

[EnJoY]

I will do that. Thanks so much for your assistance. I look forward to seeing the first reviews of this pump as well as user experiences. I'm hoping for the best.

Your fears are somewhat exaggerated. I have had sevarl blocks that utilized aluminum and never had a problem with any kind of corrosion. Use of proper inhibitors prevent any galvanic reactions.

Besides, if the entire pump is made of plastic and other relatively inert materials, why worry? It is almost like you are attacking the thing because an older model had a problem... and the problem with the older model wasnt corrosion in the first place.

The probelm with corrosion in watercooling has largely been solved, so any future cases of corrosion should be mostly attributed to either user error or ignorance, not necessarily manufacurers.

I guess the Ceramic shaft didn't take huh? re: Ruby bearings.

My "old" Powerhead has a stainless steel shaft. When I modded it, I replaced the "corroded" SS shaft, they can corrode. I don't remember off-hand.... doesn't SS react with Cu or is it Alu?

Perhaps Anti-corrosion additives is a must with this pump?

[EnJoY]

There are several different types of stain-less steel, some corrode with copper and others do not.

[Breach]

So are these ever coming out?
